I keep getting the P2197 and P0158 codes. I reset and they come back within a day or two. I cleaned the air box and MAF sensor (use K&N when off roading but not currently in). New gas cap. I am going to test the O2 sensors. Bank 2 Sensor 1 looks like passenger side before cat and Bank 2 Sensor 2 I assume is after cat passenger side.
Anyone know ohm's the sensors for this vehicle should read?
Can anyone verify locations I listed are correct? I read one post and I see the years change locations so just want to verify.
Any other tips?
Thanks for any advice
2007 GX470

 

 

Thanks for the info! Has always wondered if the O2 sensors ever go bad. I always thought the only tell tale was if you're getting bad gas mileage.
